Slice potatoes into 1/8” slices (use a mandolin slicer if you have one)
Coat 2 baking sheets with cooking spray
Line the potato slices on the baking sheets
Whisk together peanut oil and Sriracha in a small bowl (you might have to stir for a while to fully incorporate)
Brush potato slices with Sriracha/oil mixture and sprinkle with salt
Bake for 10-20 minutes (depending on how thick your potatoes slices turned out, but check on them after 10 minutes and then quite often after that to prevent burning)
